Stereo equipment, anyone?

What is the reason this community is hyper focused on headphones, headphone amps, DACs, and near field powers monitors, with very few drops going for full stereo equipment (turntables excepted)?
in particular, I wish more attention were paid to preamps. Last years’s Lineat Tube Audio MZ2 drop in the only one I’m aware of, and unfortunately I learned of it too late. And I’m fact, I have my suspicions that the real reason the MZ2 appeared here is its headphone out, and the RCA preouts may have been a mere “nice to have” feature for many.
More full size passive speakers would be nice, too!
